Examples of org.waveprotocol.wave.concurrencycontrol.common.DeltaPair.transform()

org.waveprotocol.wave.concurrencycontrol.common.DeltaPair.transform()
Transforms this pair of deltas to a new pair of deltas. If 2 deltas are the same, they nullify each other. The caller is responsible for setting the version on the result deltas. @return never null @throws TransformException

    // Deltas with same ops are the same, other info should be ignored
    assertTrue(DeltaPair.areSame(client, server));


    // Transforming the ops should result in only version update server ops
    DeltaPair pair = new DeltaPair(client, server);
    pair = pair.transform();
    assertEquals(0, pair.getClient().size());
    assertEquals(2, pair.getServer().size());
    checkVersionUpdate(pair.getServer().get(0), 1, null);
    checkVersionUpdate(pair.getServer().get(1), 1, resultingVersion);
  }

    DeltaPair pair = new DeltaPair(client, server);
    pair = pair.transform();
    // Expect the transformation of the inserts are correct. If client and server
    // have the same insert point, client op is transformed to the left of the server op.


    // Expect client inserts ".A..B."
